Modify Function
In this calculator, calculation results are internally obtained in
scientific notation with up to 14 digits for the mantissa. How-
ever, since calculation results are displayed in the form desig-
nated by the display notation and the number of decimal
places indicated, the internal calculation result may differ from
that shown in the display. By using the modify function, the
internal value is converted to match that of the display, so that
the displayed value can be used without change in subse-
quent operations.
